# This can be used to auto update your (linux) chainquery instance, keeping it up to date with the master branch.
# Minor changes might be required for the script. The assumption is that the script is run in a tmux session and checks
# a text file for changes. Whenever we push a new commit to master the text file is updated with the commit hash in
# the AWS bucket. This script checks if the last copy downloaded with the binary is different. If so it will download
# the latest master branch binary and restart the chainquery service.
